f2"efiifkndyvnffthat I, CHARLES N. SOWDEN, Y `a1o1iiZeii ofCanada, at present residing at Guantnamo, l Santiago Y de Cuba Province Cuba', havev invented anew and Im roved [Swivel Lamp-Holder,-of Which the ollow- L mgais a full', clear,V and exact description.

yinventi'on relates to'means for causing ala-mp to be automatically turned in the d1- x'ection in whichthe' vehicle is turned, so that if the vehicle is, turned to' thefrightor left, 'a Alamp will 'beturned accordingly.

itis a design;of my invention tol provide Improv-ed means for'efecting the auto- 'position to provide for changing t -Igltic turningof the lam .;v to improvethe for swlvehngfthev amp to provide :an improved spring-actuated means .tendi lyltoreturn `the lampfto .the eutral ocation ofthe; neutral posit1onrelat1vel tothe direction i Ofy travel; and to provi e actuating 'fora' pair oflamps, so arranged that turn 'automatically 'in the fdilniwhichthevehlcle turns, while the pposite :lamp

be under the control of e l operator and' subject to manually-con- -jg'olled1-meansiwhereby said opposite lamp lYf-biillmd in the opposite directionto Reference -isto be had toit 'turningof the vehicle. t a design of my invention -to imrove-in various particulars, devices of the .lndicated character, to the end ythat eiiciency .in operation may be promoted', as well as :economyv in.- manufacturing V'and simplicity of adjustment and control. distinguishing features tion,` landthe im ortant structural elements characterizing t e prefer-red .embodiment vs'lliclris illustrated, as .an-example, will be more particularly explained nthe specific descriptionl hereinafter to be. l'ven accompanydrawin'gs formin a part of this specifi- Vationyin. which sim' ar characters' ofA refer-` ence indicate corresponding parts in` all the views. 1

Figure' l is a siderelevati'on 4ofaportion' cianautomobile showing a prac-ticalembodiment. of my invention applied thereto;

Fig. 2 is a plan view of the elements shown in Fig. 1; Fig. 3 .is a transverse vertical section on a larger scale, approximately on a' linecorrespondlng with the line 3- 3 of Fig. 5; '4' is a side elevation of the vparts 5 5 of Fig. 3.

ln constructing the particular form of my shown in-Fig. 3; and Fig. 5 is a sectional plan view on a still larger sc ale, approxi? mately on' 'a line corresponding with line Sheave 13 is suitably journaled as hereinafter described at one side of the yoke, and lnppractice a second sheave 13a isprovided at the opposlte side, but only one' sheave' is 'used in practice, according to which side of the vehicle the lamp holder' is mounted. To

the sheave isv secured a depending lever 14,

to the lower, free end of which fa rope or other flexible element 15 is `secured, to rock the lever and give a partial turn to the' sheave 13, and hence a similar turn to the' yoke 10, through the ropey 12. The rope 15 passes rearwardly to an idlerfl suitably mounted as on a bracket 1 6a on the chassis 17, and extends thence transversely tothe opposite side of the vehicle, where., it vhas y suitable connection with the arm 18 of the steering knuckle 18a, inthe event the invention is applied to an automobile.

. It will be seen from the planview, that the lamp .yoke 10 and the' described appurtenances and actuating devices are duplicated at each side of the machine, .and it will beunderstood that in practice, the arms 18 j are connected in the usualmanner for operation in unison. In the present instance. I have shown the transversestretch 1 5a of the rope. as secured to a, post 19 on' an arm `187 vfor the automaticv turning of ythe .lamp- -holder with the steering devices.

The manually-controlled means'il'lustratedl -for turning thelamp holders, comprise `in the'present instance, a rope or its equivalent 21 connected to each transverse stretch 15eas at 2 0, in any suitable manner; atthepoin't indicated by the numeral 22, there 4extends a fur-ther. stretch of rope 23 tothe lower lend. of

a hand-pull or other actuating element 24,

to be actuated byhand for exerting a rearward pull on the stretch 23 and hence on the rope 2,1, and through the stretch a, on the rope 1 5, to exert a rearward pull on the latter.' y F rom the point 22 also,-or.fro1n an adja- -centpoint, therev extends from each rope 21,

-a stretch 25 of rope, lwhichV is' given a bend aroudan-idler 26 suitably supported on the i, "vehicle, andto a connection with the lower .bracket 29, nsuaL On said brack et-"isV a bed plate 30,

-lia'in end oa lever 27 or its equivalent, to be acfully explained. l The yoke 10l isSuppQrted from the chassis being secured .to the latter as is ng dependingvl brackets l31 through Wh. the pulleys 13, 13.a are journaled, as y alpin 32, the threaded end of which may receive a';nut'32.j yOn the bed-..30 a table 33 rests, in'which isjan annular groove 3e that '.receives a curved compression spring 35.

'he ends'of the spring 35 terminatev adja- "t' to astop 36 suitably secured as byv a w 36 or the like, to the table 33, the ends o the spring abutting against washers 37 (Fig. 5) that bear normally against oppo- .3.61

site sides 'of the stop 36. Between the washers 37, and fitting a curved. groove 346b inthe stopv 36, is adepending vlug 38 in fixed rela- .'tionlto the yoke 10 and depending'trom the underside thereof, the arrangement being' such that as the yoke is turned under a pull v ofthe rope 12, the lug 38 will engage one of thewashers 37,according to-the direction in which the yoke is turned, and place the spring 35 under compression. vSince. the

.ove 36b extends through each side of the 4 stop 36, the lug 38 is free to move in either --direction in response to the turning of the yoke, to vcontact with either Washer 37. The llm'za'tion of the stop 36 determines the neutral position of the spring, and in order that the location of the stopl may be changed to l .dispose/'the lampI given direction,

so as to throw its rays in a the' table 33 carryin g the saidstop. may be turned on its axis in a horiadjusted -pose a zontai plane on thebed 30, and locked in the position.v For the described purpin 39 Fig. 3) rises from the upper end of--the bracket29, extends through the l bed- 30, andl into-one of a curved series of i thej desired recesses 39a Fig.l 5) on the -under side of the table'33, it eing understood that to effect adjustment. the table 33 and its .'.supported yoke 10, with the'appurtenances,

" yarelifted od the bed 30 and replaced in the new position. Between thetable 33 and the yoke 1Q', ball vbe'a'riu'igs LlOar'e arranged and conveniently -lo,cated between opposing surfaces of said ifparts.. Similarly at the eye 41 of the swivel {'yoke 10, ball bearings 42 are arranged bcnemesi tween the surface of the said eye and the under side of the cap 43 fitting the spindle on which the yoke is swiveled. The spindle receives at its upper enda nut 45 and )am nut i6.

)Vith the described arrangement it will be seen that the stops can be so set that the light rays will be thrown in the directionof travelof the car, and by reason of the dcscribed connections between the lever 16 and thesteering knuckle, if the yvehicle is turned to the right, that lamp at the righthand side (the upper portion oi Fig. 2) will be turned to vthe right, while the tension on the cords 15, 15a of the left hand lamp will be relieved,

whereby by the manually-'controlled means (either the pedal or hand device) the left vhand lamp can be turned to the left. Thus one of the lamps will be automaticallyv turn-ed and the other will be subject to inanual control. The" stops of 'the lampscan' be vso setthat the lights when automatically turned,will.swing to the full extent that the wheels turn, and one of the lamps will, at the. same time, be always under the control of the operator, so as to be turned yin the opposite direction from that in which tl 1e i" wheels turn. i mi Having thus described my invention, l claim as new, and desire to secure by Letters Patent l. The combinationx'with a vehicle, ot a pair of lamp holders mounted to turn, con-g nection's between therespective holders'iand parts of the'vehicle'v that turn oppositely when the vehicle is turned, the turning of the vehicle in one direction'serving to turn one of the lamps in the direction in which the vehicle is turned, and manually controlled means connected with the holders and adapted to turn a holderinl the opposite direction from the automatic turning of the other holder.

2. rlhe combination with a vehicle, oli .lamp holders, means for automatically turning one holder when the vehicle is turned in one direction and forautomatically turning the other holder when the vehicle is turned in the opposite direction, the automatic turning of the holders being in the direction in which the vehicle is turned, and manually controlled means in connect-ion with each lamp for turning the same, the manually-controlled means being operative when the automatic means of a particular lamp is idle.

3. The combination with a vehicle, of 'a- I lamp holder mounted to .turn at each side of the vehicle, means for automatically turning a lamp at one side in the direction in which the vehicle turns, means for automatically turning the lamp attheothe-r side in thel opposite direction with the opposite lturning of the Vehicle, means connected with each la-mp, and operaand manuallyfcontrolledl lamp-supporting member, a curved compressionspring supported beneath the lamp-sup-v porting member and opposing the turning thereof in either direction, astop between the ends oi the curvedcompression spring, and an element on 'the 4lamp-supporting member movable into engagement with the spring at that side of the stop toward which the lamp supportingv member is turned.

5. A lamp-holder, comprising aswiveled lamp-supporting member, a curved compression sprngsupported beneath the lampsupporting member and opposing the turn ingthe'reof in either direction, a stop between the ends of. the curved compression spring, an elementon the lamp-supporting member movable into engagement with the spring at that side of the stop towardV which "the lamp-supporting member is turned, and

means forl changing the looationpof lthe said stop and the corresponding position of the Y spring.

(5. In a. lamp holder, the combination of a lyoke having a groove at the base thereof, a

tate on an axis at an angle to the axis of rotation of the yoke, a flexible element secured4 to the base of the yoke and having a partial turn thereon, and secured to the pulley and having a partial turn thereon, a levensecured to said pulley to turn the same, and means for throwing said lever. A

7. The combination in a lamp holder, of a supporting bracket, a vertical spindle thereon, ia table, means for'adjusting the table-axially and securing it in different adjusted positions, a stop on said table, a coiled -springin curved form seated on said table, Washers' at each side of the stop against which the ends of the spring abut,a lamp-holding yoke lswivel'ed on the spindle above the table .and spring, a depending member on said yoke projecting into the stop and movable against either Washer acl# oording to the direction-of turning of the yoke, and means for turning said yoke.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
